How I can share my tree with my brother, without him typing in everything again in his account ?
I have snipped info and emailed, but that is not the same.
Downloading all my data would be great.
As you probably know, your brother can see the same Deceased but neither of you can see each other's Living. There is however a possibility that you will be able to share Living PIDs in the near future. From a FS blog post regarding new features in 2023, "Another new feature will enable members of family groups to collaboratively add and share memories with one another about living or deceased relatives. They will also be able to collaborate with one another on adding facts and sources for a living relative."
You can of course, put your data into a 3rd party genealogy management program and share that.
